APPARATUS FOR COOLING BEERQO'R OTHER LIQUIOS.,

SPECIFICATION forming part of Letters Patent No. 634,792, dated October 10, 1899.

pplication filed October 1, 1898.

To atl whom it may concern:

Be it known that I, WILHELM BACHNEE, a citizen of the German Empire, residing at Stuttgart, in the Kingdom of lVilrtemberg, Germany, have invented certain new and useful Improvements in Apparatus for Cooling Beer or other Liquids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will ro enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for cooling and dispensing beer and other liquids; rand it consists, substantially, in such features ofimprovement as will hereinafter be more particularly described.

As is well known, a large number of dilerent ice-chests already exist with discharging devices for eftervescent drinks, more particuz'o larly beer and the like, in which the beer contained in a cask or in a separate container in the ice-chest is discharged by air or gas pres-- sure, and more particularly by means of carbonio acid. The majority of consumers, how- 2 5 ever, desire that no carbonio acid be used on,

the beer when drawing off the same, and the present invention is designed to meet their wishes in providing an apparatus in which the beer is discharged without carbonio-acid 3o pressure. Y

A further object of the invention is to provide means for discharging the beer through the direct pressure of a movable ice Vchest or receptacle, the eective action of said receptacle being controlled by the weight of th f\ inder or receptacle being kept tightly closed by means of a vertically-adjustable hollow piston C with Washer-rings c'.

5o piston is provided with a grate c2 and is utilized as anice container or chest.

In order that the cylinder Bv may not be The hollow` Serial No. G 92,425. (No modeld damaged when Afilling icc into theapparatus, the movableice-chest or piston C is provided at its upper part with an annular protective casing C of U-shaped longitudinal section, between the two walls ofwhich the upper part of the beer-cylinder B is received'and cannot be damaged by pieces of ice thrown into the apparatus.

The beer pumped into the cylinder stands in the samel under direct pressure owing to the weight of the movable ice-chest or piston C, together with its protective casingV C and also the ice or melted ice contained'therein, which weight may be 'increased by a WeightboxU, mounted above in the casing C and more or less counterbalanced, it desired, by means of adjustable counterweights f', supported on cords or chains F, traveling over pulleys f, supported at the upper part of the refrigerator-chest A. The cylinder B is placed in the highest part of the refrigerator-chest, which part is provided with a cover a, the said refrigerator-chest having in front a lower sideboard-like projecting part A', which is provided at' the top with a removable cover A2.

The beer in the cylinder B, which surrounds the movable ice-chest C laterally and iiows ,under its bottom e, passesat the lowest point of the inverted-dome-shaped cylinder-bottom Z2,V through an elbow-pipe t', into a second cylinder or container G, in which, with the object of attaining a further cooling, there is inserted a cooling `vessel H, which is always filled with the water resulting from the melting of the ice, which ice-Water-ows through the vessel H, which extends nearly to the bot- -tom'of the container G,vwhile from the upper part of said cooling vessel H a discharge-pipe h'conveysk the warmer water to the outside into a separate water-container N. The beer passes from the beer vessel G, by means ofla pipe g, to the draw-off tap g', and in order that the temperature of the beer when being discharged may be conveniently ascertained a thermometer K is introduced iu proximity to the draw-off tap, the tube 7c of which thermometer is immersed in the beer in the vessel G. g

In order that the amount of beer in the cylinder B and the position of the movable icechest C in the latter may at any. time be easily ascertained by the attendant, aliter-scale lil IOO arranged behind the draw-oil tap on the through the side wallof therefrigerator-chest outer wall of the ice-chest, on which scale an indicating-finger travels, which is connected with the movable chest C by a cord M, carried over a pulley m. All the positions of the said chest are therefore automatically indicated on the scale, so `that the attendant is always precisely int'ormed how much beer there is in the beer-container. In order that both the large vessel B and also the smaller beer-container G may be aerated and eventually entirely dischargedfor instance, for the purpose ot' being cleaned-an elbow-pipe D is arranged on the vessel B within the movable ice-chest or piston C, opening directly under the washer-ring c', which elbow-pipe has an air-tap d', connected by atubular nozzle, and carries below the latter a back-pressure valve d2. Said valve is normally kept closed by the back pressure of the liquid or beer in the cylinder or container B and is for the purpose' of preventing access of air to the said cylinder during the time any beer is contained in the same. The same arrangement is provided for Ithe vessel G by means of a pipe Q. opening into the same and fitted with a back-pressure valve q' and a hose-pipe tap q. In order to aerate the vessels, an air-pump or the like is connected by a hose-pipe with the back-pressure valves d2 and q', respectively, and air is forced into the vessels B and G. Then the vessel B has been first emptied, the cocks t" and i2 of the tubular connection t' between B and G are closed, and then the vessel G is subjected to pressure and emptied.

In order to till the vessel B, there is used a pipe o, mounted on the connecting-pipe t' and having a vessel O, air-admission tap o', andilling-tap o2, on the tread of which the filling hose-pipe from' the cask is screwed. The vessel O of the filling-pipe and the tap q for discharging the vessel G are arranged in a separate chest or box A3, placed at the side of the sideboard-like projection Al in proximity to the draw-off tap g in such a way as to be concealed from view, said box A3 being easily removable.

In order to draw ott the waterprod uced by the melting of the ice from the movable icechest or piston C into the water vessel I-I suspended in -the beer-container G, a suctionpipe E is employed, which extends upwardly over a pulley e at the top of casing C', with one end thereof reaching to the bottom of said movable chest C. Said pipe is protected from injury on the inner side of said casing by means of a sheathing c2, fastened to the latter, and it (the pipe) is connected at its other end with the chamber of a pump NV or other exhausting device Reaching from said pump and extending almost to the bottomV of the Vessel H is another pipe or tube E,thro ugh which the cold Water pumped from the movable ice-chest is caused to pass into said vessel, while the warmer water is carried off from the top of the latter by means of a pipe 71,. The spindle of the pump W is carried and has a hand-lever w outside the said chest for operating the pump. A large door T is arranged on the rear wall of the ice-chest A to allow ot' the cylinder B being inserted or removed-for instance, for the purpose of cleaning. In order that the tap t2 of the tubular connection 'L' may be conveniently opened after the opening of the door T, the key or lever t3 of the same isv provided with a linkt, the handle of which lies in front in proximity to the door T, so that by pulling or pushing the link 4 the tap t2 may be easily opened or closed.

Where the cylinders I3 are very large, it may be advisable in. certain circumstances to arrange a separate. ice-container in the ordiynary manner. in the upper part of the icechest A or in a construction arranged at one side, which is not shown in the drawings, so that the cylinders B may also be cooled by means of cooled air from the outside. Generally speaking, any further cooling is unnecessary.
